Email address is not updating after 2.7.6 update.

[sacordero]

Description: Email address is not updating after 2.7.6 update. The User Sync Tool has started throwing errors that it can't update the email attribute of users with the following error: "code: "error.user.nonexistent" message: "User Id does not exist: [email protected]"".

Steps to reproduce
Customer indicates, Students have accounts in the format “[email protected]”. When they are hired as employees, their primary email alias is updated to the format “[email protected]”. For the past 2 years, the UST has been correctly updating the email address. They just updated from 3.7.5 to 3.7.6 and now this issue has occurred.

Testing
Customer has tried updating to 2.8.0 and the issue still persists, but after rolling back to 2.7.5, all the errors disappeared. They have checked [email protected] and the email was successfully updated to [email protected].

Logs indicate this is the case.

Customer believes the fix #808 had an unintended side effect.

Environment
UST version: 2.7.6
OS type and version: Win Server 2012
